White/blank screen in Workspace after updating to workspace 19.10.1 from viewer/receiver 12.9.1 (because of update to Macos 10.15)


thomas christinck

Question

Everything was running on the Mac client with receiver 12.9.1 installed:

- starting in browser rda.company.com with user/password/token für vpn

- a new viewer window opens

- in the window windows is starting ...

 

After the Macos update to 10.15 Catalina, I needed to update from receiver to workspace.

- I installed 19.10

- meanwhile I updated to 19.10.1

- always same behavior:

-- a new viewer windows opens

-- window is complete white

-- Although I cannot see anything, I can click an work  (After reconnecting that session o another computer I see that I changed things while clicking around  on the white screen)

What can I do on the client?

What can I ask my server administrators? (they suggest wokring in the browser ... no, that is no alternative, that has too many problems)

 

Thanks

I was able to get past this by using the following in Terminal:

 

defaults write com.citrix.receiver.nomas PreferMetalRendering -bool NO

 

Unfortunately still unable to get the desktop to go full screen.

Thank you so much! I did not find the "PreferMetalRenderung with my search words ...

My Workspace/CitrixViewer 19.10.1 now runs like a charm.  All colors there.
I have no probs with maximizing the viewer window to fullscreen.

Was having same exact issue since I upgraded to Mac OS Catalina.  My IT Dept's response was to tell others not to upgrade to 

Mac OS Catalina...  This resolved the issue and I can access our network again using Citrix.  Thanks!

It should work for you.

The problem was the workspace app.

Catalina is indirect involved, because 32-Bit apps like the receiver are not working any more.

The workaround should work with the workspace on mojave as well as on catalina.

 

And in any case:

You can undo the change with an "YES" at the end of the command.

or: a complete uninstall of workspace and a fresh installation of workspace brings my machine back to the original state (white screen) and I had to enter the command with "NO" at the end.
